The recently introduced TLS telescopic linear axis system from linear motion system specialist ROLLON is a two- and three-stage solution for automation in confined spaces. Thanks to the particularly compact design, long strokes with high loads can now be handled even in very limited spaces. According to ROLLON, this makes the new Telescopic System an ideal solution for applications where the travel path of the axis exceeds the distance between the machine and the ceiling or wall.

The use of low-cost extruded aluminium profiles in combination with highly rigid recirculating ball bearing guides and rack and pinion drives is intended to achieve optimum performance with high cost-effectiveness. Abrasion-resistant polyurethane toothed belts serve to synchronise the individual stages. An automated lubrication system also ensures a long service life and low maintenance. The compact design is very space-saving and enables efficient use of space. For comparison: with a stroke of 1,200 millimetres, the installation length with a conventional axle from the Plus system (SC160) is 2,000 millimetres; with the TLS280 it is only 1,095 millimetres. This means that only about half the installation space is required.

The TLS system is suitable for both vertical installation (limited ceiling height) and horizontal installation (limited lateral installation space) and realises strokes of up to 3,000 millimetres and loads of up to 450 kilograms. Variants with strokes on both sides are also available. When installed vertically, the systems achieve speeds of up to six metres per second and accelerations of up to twelve metres per square second with a repeat accuracy of plus/minus 0.05 millimetres. If the telescopic linear axis system is installed horizontally, accelerations of up to 20 metres per square second with a repeatability of plus/minus 0.03 millimetres are possible at the same speed.

The new ROLLON Telescopic System is versatile, including machine loading or assembly automation, and integrates seamlessly into multi-axis configurations. In the three-stage variants, the individual stages are synchronised exclusively via toothed belts. This predestines them for use in highly dynamic applications, for example for loading press tools. If, on the other hand, high masses are required, the hour of the two-stage systems has come. The combination of toothed rack on the gearbox and toothed belt in the synchronisation of the second stage makes them particularly robust.
